What is RPC MCP Server?

RPC MCP Server is a Model Context Protocol server implementation for interacting with any EVM-compatible RPC endpoint. It provides a standardized interface for AI models to interact with Ethereum and EVM-compatible blockchains. It is designed for developers using AI assistants like Cursor to query blockchain data.

How to use RPC MCP Server?

Install via npm (npm install -g .), set the RPC_URL environment variable to your RPC endpoint, then add the server to your Cursor mcp.json configuration. The server exposes tools like eth_blockNumber, eth_getBalance, and eth_call that can be invoked through the MCP client.

Key features of RPC MCP Server

• Support for any EVM-compatible RPC endpoint
• Get current block number
• Check account balances
• Get transaction counts (nonces)
• Retrieve block information
• Get transaction details
• Make contract calls

Use cases of RPC MCP Server

• Query blockchain state directly from an AI coding assistant
• Monitor account balances or nonces during development
• Debug transactions by fetching block and transaction details
• Call smart contract functions without leaving the IDE
